APPARATUS FOR CLEANING SANDPAPER OR SAND-BELTS.

esarro.

To all whom it may concern:

Be it known that l, HARRY HEADY, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Apparatus for Cleaning Sandpaper or Sandlielts;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in apparatus for cleaning sandpaper or sand belts, especially those used on machines and which havebecome choked by gathering fine particles of the material on which itoperates.

The object of the invention is to prolong the usefulness of the sandpaper or sand belt by removing therefrom the embedded saw dust.

Another object of the invention is to provide an apparatus for washingsaw dust from sand paper or sand belts and thereby restore itseffectiveness.

A further object of the invention is to provide a simple and inexpensivemachine which will thoroughly clean sand paper or sand belts ofcollected saw dust without destroying its value by removing the sand.

With the above and other objects in view the invention consists incertain combination and arrangement of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

ln the accompanying drawings forming a part of this specification and inwhich like characters of reference indicate corresponding parts, Figurel is a perspective view embodying my invention; Fig. 2 is a plan view ofsame; Fig. 3 is an end view, and Fig. 4: illustrates details of a springcatch.

Referring to the drawing, in which is illustrated the preferredembodiment of my apparatus, consisting of a frame 1, having cornersupporting legs 2, which are connected by suitable braces 3.

The ends of the frame 1 are provided with centrally located bearings 4for receiving trunnions 5, secured to the under side of a table 6,having vertical transversely extending end strips 7. Secured to one ofthe trunnions 5 is a cog-wheel 8, which is engaged by dogs 9 pivoted tothe frame on opposite sides of said cog-wheel to hold the table 6,

which may be rocked by means of a crank lever 10, in any adjustedposition.

The table (3 is preferably covered with sheet Zinc or copper, and isprovided with a plurality of spring catches adapted to securely holdsand paper or a sand belt 11 during the washing operation. The springcatches consist of flat curved springs 12, having slots 13, which allowthem to be moved loi'igitudinally on pins 1 projecting from the table,for holding different widths of sand paper. Pivotally connected to thepins are buttons 15, having bosses 16 on their under sides for engagingthe springs as the buttons are turned to cause said springs to clam saidsand paper or sand belt.

A centrally located spraying pipe 17, pro vided with apertures 18,extends longitudinally just above the surface of the table 6, and isconnected to a pipe 19, provided with a valve :20, leading to the lowerportion of a hot water supply tank 21, adapted to be heated in anysuitable manner. The tank 21 is provided near its top with an inlet pipe22 and an overflow pipe 23.

On each side of the frame 1 are inclined sheet metal troughs 24:, havingconnected to their lower ends pipes 25 leading to a waste pipe 6, forcarrying away the water caught by the troughs from the table 6 and fromthe water overflow pipe 23.

Extending from the lower portion of the tank 21 is a short pipe 27,furnished with a valve 28, and having connected thereto a flexible tube29, to which is attached a triangular shaped spraying nozzle 30,terminating in an elongated narrow mouth 31.

In order to wash sand paper or sand belts by the herein describedapparatus, the same is secured to the table by the spring catches, andthe valve 20 opened to allow the hot 'ater from the supply tank to flowover it. The table is rocked by means of the crank lever 10, so that theloose saw dust freed from the sand paper will be washed into the troughs24. The table may be held in an adjusted position by the dogs 9 engagingthe cog wheels 8, and the spraying nozzle 30 manipulated to further washthe saw dust from the sand paper or sand belt. When the sand paper orsand belt has been thoroughly washed, it is removed from the table anddried in any suitable manner.

Although the elements herein shown and described are well adapted toserve the purposes for which they are intended, it is to be understoodthat slight changes may be made in the precise construction set forthWithout departing from the spirit of the invention.

Having thus fully described my invention,

What I claim and desire to secure by Letters Patent is:

1. In an apparatus for cleaning sand pa per, the combination of a table,means on the table for holding the sand paper and means for sprayingfluid over the sand paper.

2. In an apparatus for cleaning sand pa- 3per, the combination of atable, spring catches on the table for holding the sand paper, a hotWater storage tank, and a pipe leading from the tank for spraying hotWater over the sand paper.

5 3. In an apparatus for cleaning sand paper and sand belts, thecombination of a table tiltably mount-ed on the frame and spring catcheson the table for holding the sand paper or sand belt, a hot Water supply'tank, and a pipe leading from the tank and extending longitudinallyabove the table for spraying the sand paper or sand belt.

at. In an apparatus for cleaning sand pa per or sand belts, thecombination of a ta- 1' 'ble having trunnions rotatably mounted on aframe, a crank lever applied to one of the trunnions for tilting thetable, a cog-Wheel on the trunnion, dogs pivoted on the frame forengagingthe cog-Wheel to hold the table i in locked position, springcatches on the table for holding the sand paper or sand belt, a

hot water supply tank, and a pipe leading from the tank and extendinglongitudinally above the table for spraying the sand paper or sand belt.

5. In an apparatus for cleaning sand paper or sand belts, thecombination of a table tiltably mounted on a frame, spring catches onthe table for holding the sand paper or "sand belt, a hot Water supplytank, a pipe leading from the tank and extending longitudinally abovethe table for spraying the sand paper or sand belt, troughs at the sidesof the table for catching the water from the ply tank,

table, and Waste pipes leading from the troughs.

6. In an apparatus for cleaning sand paper or sand belts, thecombination of a table tiltably mounted on a frame, spring catches onthe table for holding the sand paper or sand belt, a hot Water supplytank, apipe leading from the tank and extending longitudinally above thetable for spraying the sand paper or sand belt, troughs at the sides ofthe table for catching the Waste Water from the table, an overflow pipeleading from the tank to one of said troughs, Waste pipes leading fromthe troughs, a second pipe leading from the supply tank, a flexible tubeconnected to the second pipe, and a spraying nozzle on the flexibletube.

7. In an apparatus for cleaning sand paper and sand belts, thecombination of a table having trunnions rotatably mounted on a frame, acrank lever applied to one of the trunnions for tilting the table, acog-Wheel on the trunnion, dogs pivoted on the frame for engaging thecog-Wheel to hold the table in locked position, pins projecting from thetable, curved springs having slots for receiving the pins, buttonspivotally mounted on the pins adapted to exert pressure on the springswhen being turned, a hot water supa pipe leading from the tank andextending longitudinally above the table for spraying the sand paper orsand belt, troughs at the sides of the table for catching the Water fromthe table, an overflow pipe leading from the supply tank to one of saidtroughs, Waste pipes leading from the troughs, a second pipe leadingfrom the supply tank, a flexible tube connected to the second pipe, anda spraying nozzle on the flexible tube.

In testimony whereof I aflix my signature in presence of two Witnesses.
